Present Indefinite и Past Indefinite Tense. (не менее 5 предложений.) Choosing a career is like any other activity; it is best to work to a plan. Too many people start looking for a specific job before thinking out their occupational aims. It is a good idea to begin by attempting to define in clear terms what your requirements are from a career. This involves taking a realistic view of your strengths and weaknesses. You may think for example, that you would like a job which involves organizing people, but liking such a job is not a sufficient justification if experience you already may have suggests that this is not your strong point. On the other hand, you should remember that training will equip you to do new things. A further point to consider is how far you will be willing to do for a time things which you do not like knowing that they are necessary to achieve your longer term objectives. Having thought carefully about the sort of person you are, try to work out a realistic set of occupational requirements. In particular, you can answer to important questions. First: what sort of life do you want to lead? For example, do you want to live in the country or in the town? Is leisure time of great importance to you? Is the size of your salary important? Do you want to put down roots or travel widely? Second: what sort of work do you want to do? For example, do you like working alone or with others? Does teaching people appeal to you? Do you want to be an organizer of other people's activities?
